"choice" is a useful high-level abstraction of certain phenomena. It's a lossy abstraction, and if you had infinite amounts of memory and computing power, you would have no need for it, at least when reasoning about other entities. It exists, in exactly the same way in which books (the concept of a book is also a high-level abstraction) exist.
If that sounded wrong or like nonsense to you, please taboo "choice" and explain what exactly your question is.
I also have a question of my own, regarding the rock-hill-system:
How does this isolation work? Do you assume that the forces acting on the system from outside stay constant (in some undefined fashion), without explicitly modeling the outside? If I assume *no* further interactions with the outside, I don't expect to see the rock rolling down the hill, since there's no planet below to gravitationally attract it. Or was the planet supposed to be part of this system?
